Abstract

"BUCHAS PARA ESTEIRA E MéTODO E APARELHO PARA A FABRICAçãO DAS MESMAS". Camadas temperadas são formadas sem irregularidades na superfície circunferencial interna de uma bucha para esteira apresentando um diâmetro interno reduzido ou nas superfícies circunferenciais internas de duas ou mais buchas para esteira que ficam submetida a têmpera numa condição sobreposta. Para introduzir um meio para resfriamento para resfriar a superfície circunferencial interna das buchas para esteira, um tubo orientador apresentando um diâmetro externo menor do que o diâmetro interno das buchas para esteira fica disposto no lado da superfície circunferencial interna e o meio para resfriamento introduzido pelo tubo orientador é desviado por um membro desviador apresentando uma superfície esférica ou uma superfície curva similar, de maneira tal que permite-se que o meio para resfriamento flua numa direção essencialmente paralela a uma direção axial das buchas para esteira 1 dentro de um espaço definido pela superfície circunferencial externa do tubo orientador e a superfície circunferencial interna das buchas para esteira, desempenhando assim um resfriamento por fluxo laminar."BUSHES FOR MAT AND METHOD AND APPARATUS FOR THE SAME MANUFACTURE". Tempered layers are formed without irregularities on the inner circumferential surface of a track bush having a reduced inner diameter or on the inner circumferential surfaces of two or more track bushings that are quenched in an overlapping condition. To introduce a cooling medium to cool the inner circumferential surface of the belt bushings, a guiding tube having an outside diameter smaller than the inner diameter of the belt bushings is disposed on the side of the inner circumferential surface and the cooling medium introduced by the tube. The orienting member is deflected by a diverter member having a spherical surface or similar curved surface such that the cooling medium is allowed to flow in a direction essentially parallel to an axial direction of the belt bushings 1 within a space defined by the surface. outer circumferential direction of the guiding tube and the inner circumferential surface of the belt bushings, thus performing laminar flow cooling.
